Is the binomial x-9 a factor of 4x^3-28^2-36x-27

No

Step-by-step explanation:

If (x - 9) is a factor then x = 9 is a root and f(9) = 0

f(x) = 4x³ - 28x² - 36x - 27, hence

f(9) = 4(9)³ - 28(9)² - 36(9) - 27

     = 2916 - 2268 - 324 - 27 = 297

Since f(9) ≠ 0 then (x - 9) is not a factor of f(x)

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

ok so what's the question?
